Milling of Porous Silicon Microparticles SpringerLink

Pre-milling preparation of the porous silicon involves reducing the membranes to fragmented flakes, typically around 10 mm 2 (shape is not important), that can conveniently pass through the hopper en masse – this can be achieved by manually shaking the flakes in a sealed plastic pot, for example. The prepared flakes are fed into the mill via the hopper at a predetermined rate
